Abstract
The present commercial Electromagnetic induction (EMI) instruments applied for soil mapping have some limitations. Due to the lack of robustness in calibration of EMI instruments, the quantitative measure of apparent electrical conductivities has not been yet possible. We introduce a novel method, for calibration of EMI systems in which the EMI loop antennas are modeled using antenna transfer functions. We performed EMI measurements over the saline water with different increasing conductivity values under controlled laboratory conditions. Inversion of the model permits to retrieve conductivity of the water appropriately. This approach appears to be promising for estimation of apparent electrical conductivity.
